OpenStudy (anonymous):

with

OpenStudy (anonymous):

Find the solution set for the equation, given the replacement set. y = 4x – 8; {(5, 5), (3, 4), (4, 7), (2, 2)}

OpenStudy (anonymous):

plug the points in and see what one makes the statemement true.

OpenStudy (anonymous):

4(5) - 8 << correct ?

OpenStudy (anonymous):

yeah, and then it should equal 5, if t doesnt then go on to the next one.

OpenStudy (anonymous):

a. {(2, 2)} c. {(4, 7)} b. {(3, 4)} d. {(5, 5)}

OpenStudy (anonymous):

it would be "D" right ?

OpenStudy (anonymous):

|dw:1365776159836:dw|

OpenStudy (anonymous):

lol okaa

OpenStudy (anonymous):

so try the next one.

OpenStudy (anonymous):

4(3)-8 = ?

OpenStudy (anonymous):

what will that give you?

OpenStudy (anonymous):

Which Is 12-8=?

OpenStudy (anonymous):

yess which is 4, so yes that pair works.

OpenStudy (anonymous):

OpenStudy (anonymous):

yupp!

OpenStudy (anonymous):

oka .. thanks :) help with one more ?

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

well what is a relation?

OpenStudy (anonymous):

idk :/

OpenStudy (anonymous):

but i do know that for every input there has to be a output

OpenStudy (anonymous):

when 1 x value has only 1 y to it.

OpenStudy (anonymous):

you can also graph the points

OpenStudy (anonymous):

Is The Input The X's & Output The Y's?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

C ?

OpenStudy (anonymous):

i would probably go with b since not all the inputs have an output.
